McGuire Ballistics 6.5 PRC load workup!

59 is it! Time to test at distance now. Looking like a potent setup!

I ran the numbers afterwards and man... this might be the one I use this fall if everything checks out

Awesome. Some of the easiest loading I've done, are with these bullets. They put game down too!

I'm finding out the same! Only taken a couple critters with the McGuires so far but this is the 3rd load workup with them and it's been pretty dang easy.

I am using N560 as well with my 6.5PRC's and the 125 MBCR. My rifles show the
clicker issue pretty early as I end up at 56gr with one and 54gr with the other, 3150fps and 3080fps. Setup a temp table(Kestrel) for the loads and you should be good to go.

Great feedback

Got out to the range to zero and check my drops. So far so good!

Checked my muzzle velocity again too, started the morning off at 28 degrees F.

4 shots
Average - 3246
ES - 20
SD - 9.0




After a brief cool down and checking zero on another gun we were off to distance. Checked at the following ranges that I had steel at and everything lines up with my drop chart I made using the advertised BC (.600 G1), current muzzle velocity, sight height, and a good 100 yd zero.

Yds - Strelok ballistic solution (what I actually dialed)

400 yds - 4.3 moa (dialed 4.25)

552 - 7.6 moa (dialed 7.75)

785 - 13.6 (dialed 13.75)



This has been about as easy of a load workup as I've done. I'm just going to keep practicing and documenting in the process. Besides ordering another batch of bullets there is not much left to do. Probably test temp stability of N560 on a hot day when they get here.

I'd have no reservations about hunting with it today! All shots were first round impacts at said yardage.
